Liverpool make the trip to Portugal to continue their winning start in the Champions Leagu e group stage campaign as they take on Porto who are searching for their first win in the competition this season.
After a dramatic 3-2 comeback victory at Anfield over Italian giants AC Milan, momentum is with Jurgen Klopp's side who harbour aspirations of securing the seventh Champions League title in their history.
In terms of how the Reds will line up, Klopp has the luxury of having the majority of his first-team stars to choose from, with the German boss admitting his surprise at the fact every member of the Liverpool midfield is fully fit and available for selection.
"In midfield it's a rare moment they are all fit and I have to make a few decisions", Klopp revealed, before going on to explain how he comes to his decision over who he will deploy in the middle of the park for every contest.
"And then it is about the players who are involved in the three or the four or whatever in terms of the midfielders we line up with.
"You can only do that in the training sessions and it's not criticism, it's just the way it is. Even when you're really good in training you have to be especially good to be one of the three to make the last line-up.
"I am completely open and I don't start any kind of week where I know what I will do against them or them."
It is not all good news for Reds fans, as Trent Alexander-Arnold has not made the trip to Portugal - despite taking part in an open training session on Monday afternoon.
The reason for the England international's absence have not yet been made clear, having played the full 90 minutes against Brentford on Saturday evening.
While he will no doubt be annoyed he won't be out there with his teammates in Portugal, the right-back has enjoyed a promotion within the Liverpool dressing room in terms of authority.
Will Trent be sorely missed against Porto? Comment below.
Alexander-Arnold was named as one of Liverpool's six captains, the leaders within the ranks.
Issuing update on the situation, Klopp said: "We had three captains in Hendo, Milly, Virg and the players voted for another three.
"So that was won by Trent, Robbo and Alisson Becker."
Liverpool's predicted starting eleven vs Porto: Alisson; Gomez, van Dijk, Konate, Robertson; Henderson, Fabinho, Milner; Mane, Jota, Salah.
